Exam 300-430 topic 1 question 223 discussion

The allow AAA override setting must be enabled on the WLAN to allow the policy to work correctly. This setting ensures that the Cisco ISE (Identity Services Engine) can apply the URL redirection and other attributes (such as ACLs) defined in the RADIUS response to the client. In this case, the RADIUS response includes a URL redirect for BYOD devices that are not registered to the Mobile Device Manager (MDM). Explanation of the options: A. static IP tunneling: This is used for assigning static IP addresses to clients through tunneling and is unrelated to URL redirection or AAA override. B. allow AAA override: This is correct. Enabling this setting allows the WLC to accept and apply attributes (such as URL redirection and ACLs) sent by the RADIUS server (Cisco ISE) in the Access-Accept message. C. RADIUS profiling: This is used for device profiling based on RADIUS attributes but is not required for URL redirection or AAA override. D. Aironet IE: This is used for Cisco Aironet-specific information elements in the wireless frames and is unrelated to URL redirection or AAA override.
